How many protons electrons and neutrons respectively does 29 CS have

irakobra [83]

$55 \; \text{e}^{-}$ , $55 \; \text{p}^{+}$ , and $74 \; \text{n}^{0}$ - in case cesium-129 is what you were referring to.

Cesium has atomic number $55$ as seen on a modern periodic table. A cesium atom nucleus would thus contain an equal number of protons; in addition to that, a <em>neutral</em> atom of cesium would contain the same number of electrons in its electron cloud.

For a particular isotope,

$\text{Mass number} = \text{Number of protons per nuclei} + \text{Number of Neutrons per nuclei}$ .

This isotope of cesium has a mass number of $129$ and contains $55$ protons in each atomic nucleus. One cesium nuclei would therefore contain $129 - 55 = 74$ neutrons.

Which is the term for the different forms of a gene for a given trait?

elena-s [515]

Answer:

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
